[tex]\text{We need to find the area of the circle with its circumference given}\\\\\text{The equation for this is:}\\\\A=\frac{C^2}{4\pi}\\\\\text{In this case, we would use 3.14 for pi, so your equation is:}\\\\A=\frac{C^2}{4(3.14)}\\\\\text{Plug in your circumference and solve:}\\\\A=\frac{119.32^2}{4(3.14)}\\\\A=\frac{14,237.2624}{4(3.14)}\\\\A=\frac{14,237.2624}{12.56}\\\\\text{Divide:}\\\\A=1,133.54\\\\\boxed{\text{The area is 1,133.54}\,\,cm^2}[/tex]
